Cashner, coming off a start against the Mets where he allowed five earned runs in 5 1/3 innings, put a lot of traffic on the bases against the Brewers. But, generally, he found a way to wiggle clear of too much damage.
"I didn't keep out of trouble the whole game," said Cashner, who stranded eight.
Cashner couldn't pitch around two leadoff extra-base hits -- a Scooter Gennett double in the third inning and a Shane Peterson triple in the fourth inning. Both came around to score as the lone runs Cashner would allow.
"He wasn't perfect, he wasn't his best, but the Brewers had timely hitting, they hit in the clutch, they had two-out hits. That's what it's about," said Padres interim manager Pat Murphy.
A fine defensive play by center fielder Melvin Upton Jr. in the third inning saved a run, as Adam Lind tried to score on a Khris Davis single that had already knocked in one run.
